background: in recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. in this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

Introduction: Although formalin-induced activity in primary afferent fibers and spinal dorsal ‎horn is well described, the midbrain neural basis underlying each phase of behavior in ‎formalin test has not been clarified. The present study was designed to investigate the nucleus ‎cuneiformis (CnF)‎‏ ‏neuronal responses during two phases after subcutaneous injection of ‎formalin into the hind paw...

Ljiljana D. Mili c and Miroslav D. Lutovac Abstract|The IIR realizations of the Hilbert transformer require less computations than FIR realizations, but the main disadvantage of the minimum phase IIR realization is the nonlinearity of the phase characteristic. In this paper, we show that using allpass IIR sub lters from the minimal phase solution it is possible to design an IIR Hilbert transfor...

This paper proposed a simple technique to design Linear Phase Infinite Impulse Response (IIR) filter. The design problem is formulated as linear equation problem, which uses a frequency domain sampling of the desired Magnitude and Phase response of filters along with optimal solution of linear equations to obtain the filter design. The proposed method can give the best result if we increase the...

A group delay-based excitation source analysis and design method is introduced for extension of TANDEM-STRAIGHT, a speech analysis, modification and synthesis system. This introduction makes all components of the system be based on interference-free representations. They are power spectrum, instantaneous frequency and group delay representations. This unification has potential to solve the majo...
